I konw the preflop call is debatable, I don't really like playing these hands OOP against unknown players.
On the flop I checked with the intention to checkraise any reasonably sized bet all-in. but after that raise the FE is gone. If one of them has a set or the higher flush draw my draw doesn't look that hot anymore.
